Abstract
ABSTRACT OF THE DISCLOSURE
A dispenser for paste products, comprising a container and a hollow dispensing head having a pumping member mounted on its interior, an actuating lever for said member, and a delivery conduit which is associated at one end with the pumping member.
The head has a tubular extension facing the top end of the container of which it matches the contour and wherein means are provided of releasable attachment to the container, thereby the latter can be provided in the form of a replaceable refill container. To extend the working life of the dispensing head, the pumping member has a leaf spring associated therewith which acts against the push force from the actuating lever.

Description

DESCRIPTION
This ;nvention relates to a dispenser of paste products, paPti~ularly but not exclusively of toothpaste, being of a type which comprises a tubular container having a vertical lengthwise axis, a hollow dispensing head located on the top end of the container, a bottom wall slidably movable inside the container in tight relationship therewith in one direction toward the head, a pumping member placed near the top end of the container, a sleeve having one end free and the opposite end associated with the pumping member, an actuating lever f~P pressing the pumping member, said lever being mounted on said head and movable angularly from a home position to a product dispensing position, a delivery conduit having an inlet port and an outlet port and being mounted rigidly in the head, said actuating lever being provided with a cam profile for engagement with said free end of the sleeve, said delivery conduit being axially slidably connected to said sleeve through its Inlet end, said pumping member comprising a flexible annular membrane with a radially outward edge and an inward edge, the latter edge being connected to said sleeve.
A dispenser of the above-outlined type is shown in European laid-open Patent Application No. 286,608, for example.
As may be seen, the dispenser known from that European Appl;cation provides for the tubular body of the container of paste product to be dispensed to also define, in its upper portion, a housing for the operational members, specifically for the pumping member, the delivery conduit, and the actuating lever.
It will be appreciated, accord;ngly, that once the container has been emptied, the dispenser can no longer be re-used, and must be disposed of. In this way, however, a dispenser portion is also thrown away unavoidably which is technologically more intensive, such as the dispensing head together with its components and mechanisms.
It is an object of this invention to provide a dispenser which allows its dispensing head to be re-used for a given number of times, by replacing the empty container with a fresh one.
This object is achieved by a dispenser as indicated being characterized as set forth in Claim 1.
To provide for extended working life of the pumping member, as well as for the possible use of non-elastomer materials in its construction, a preferred embodiment of the dispenser of this invention is further characterized in that said head includes an elastic bias means acting on said pumping member against the push force from said actuating lever.
The-inventipn will be now described in greater detail with reference to a preferred, non-limitative embodiment thereof, shown in the accompanying drawings, where:
F;gure 1 is a partly cut away view of a dispenser according to the invention;
Figure 2 shows, in axial section and to an enlarged scale, the dispensing head;
Figure 3 is a partly cut away side view of a container in its form as a refill container;
Figure 4 is a plan view of a la2f spring for the pumping member; and ~;~ q i t~ b ~
Figure 5 is a sectional view of the Leaf sprins taken along V-V in Figure 4.
With reference to the drawing views, generally shown at 1 is the tubular container of a dispenser according to the invention which is provided with a bottom wall 1a conventionally adapted to be moved upwards through the container as the paste product is being dispensed. Generally indicated at 2 is the dispensing head of hollow construction. This head comprises a removable proteGtive cap 3 which fits over a structure 4 whereto the delivery conduit 5 is attached. An actuating lever 6 is linked to said structure 4 by means of a pivot pin 7 such that it can perform angular movements about said pin which will take its shank 8 away from the edge 9 of the structure 4.
The lever 6 is also provided with a lip 10 which, with the lever at itsihome or~rest position as shown;in:Figurei1, covers the outlet port 11 of the delivery conduit 5 having, at its opposite end, an inlet port 12 on a conduit section 13 which extends along the longitudinal axis X-X of the head and the whole dispenser.
This section 13 of the delivery conduit 5 engages, for axial sliding movement, with the sleeve 14 associated at a central location with the pumping member consisting of a flexible annular membrane 15. The sleeve 14 has a free end 16 intended for co-operation with a cam surface 17 fast with the lever 6, to operate the pumping member in the manner disclosed, for example, in the aforementioned European Patent Application.
In accordance with this invention, the radially outward, peripheral edge 18 of the membrane 15 is held by the inner wall of the head structure 4, where it engages in an annular L; ~ ', r ,~
groove 19 effective to inhibit any axial movement thereof.
Associated with the membrane 15 is ;D accordance with a preferred aspect of the invention, a leaf spring.20.
~ With reference in particular to Figures 2, 4 and 5, this leaf springiis ring-shaped so as to encircle the sleeve 14, whereon it engages against a peripheral ridge 21. The opposed terminating portions 22 and 23 engage against the inner wall of the structure 4 in the groove 19, for the necessary reaction.
The dispensing head portion facing the top end 24 of the container 1 has a tubular extension 25 formed with a threadway 24 on its inside. This extension 25 duplicates the peripheral contour of the top end 24 of the container 1, which end is provided with a mating threadway 27.
The mutual engagement of the threadways 26 and 27 provides a releasable connection between the dispensing head 2 and the container 1.
The mating threadway 27 is, in particular, used for attaching a cover 28 which imparts, to the container 1 prior to ;ts use in combination with the head 2, the appearance and function of a refill container.
The advantages and merits of a d;spenser according to this invention should be apparent from the foregoing description and illustration of its operation.
After the amount of the product supplied in the container on first purchase of a complete dispenser has been depleted, the user may separate the container 1 from the head 2 and replace it with a fresh container while saving the head itself, which evidently constitutes the most expensive portion of '~ ' 3 -- 5 - f~ ;3 . ii such a dispenser unit, with obvious benefits from the economic standpoint~
Th~ leaf spring ZO is contributive toward an extended working life of the head, and where a non-elastomer material is used in the construction of the membrane 15, also to provide the required elastic bias for the membrane.
